Patented Oct. T30. 1231 4 To all whom it In (11 (O/1.06771.

Be it known that I. ()rro "ifisntna, a subject of the King of Prussia, residing at Copenik. Germany, have invented certain new and useful Improvements in (ooling Devices for Revolving Motors, of which the following is a specification.

This invention relates to internal combustion engines of the multicylimler type in which the cylinders revolve around a sta tionary shaft. This class of engines is now largely used for driving lying machines. as the rapid revolution of the motor tends to keep it cool. The ap 'ilication oi eater cooling to such an engine is stnnewhat ditficult if the circulation is to he maintained by a pump, while the thermo-siphon principle is equally impracticable owing to the constant change of position of the cylinders. Moreover. in the water cooling; systei'ns which have been devised for such engines it has been customary to surround each cylinder with its own jacket to wh'u'h the water is fed independently of the others. With that arrangement, however. there is a possibility that one jacket the y bet-time leaky and cause its cylinder t run hot, thus putting the entire engine out 0'? commission. urthermore, the radiator is bulky and heavy. The present invention aims to obviate these ditliculties, by connecting all .the waiter jackets to an annular radiator ot moderate dimensions, and by arranging the connecting passagesso that circulation is maintained by a combination of thermo siphon and centrifugal forces, as hereinafter set forth and particularly pointed out in the claims.

In the accompanying drawing, Figure l is a front elevation of a revolving motor equipped with my improved water cooling system, and Fig. 2 is a crosssection of the same on the line AB+G, Fig. 1.

he motor is represented as having tive cylinders 1 arrangedradially around a central stationary shaft 2 and spaced equidistantly. Each cylinder has a water jacket 3, and adjacent to all of said jackets is an annular radiator 4 concentric with the shaft 2 and located preferably near the inner ends of said cylinders so that the outer ends of said cylinders extend radially beyonefl. said radiator. The outer end of each jacket 5 is connected by a pipe 5 with the outer portion i l l i l l i l l in. the radiator nects the inner portion. thereof with the inner end of said water iatket.

The operation is as t'ollo\vs:---".l"hc water in the radiator is colder than that in the jackets and is consequently heavier. The action of centrifugal force, as the motor revelvee. throws this colder heavier water out through the pipes 5 to the outer ends of the jackets 3. where it displa. the lighter heated water and forces it inwardlv along through the jackets to the iuiier pipes 41, by which it passes to t radiator and there becomes cooled. The operation is thus in effect that of a thermo-siplmn system, but the ole radiation is effected hr centrifugal force instead of by gravity. 4

"in. case a. et'linder o jacket becomes detective, so that. its water leaks away, the supply of cooling; thud is supplemented from the others. so that the jacket cannot becon'ie empty, and the Tina-- chine is prevented from running hot. The radiator is convenient and is at: rssib e for inspection and repai In accordance with the on, 'sions of the patentstatutes. I have dest need. the primer ple of operation or" in invention, tote with the a iparatus which i now cousin represent the best enibodinmt-t thereof; out I desire to have itunderstood that the apparatus shown is only illustrative, and that the invention car he carried out or otl'ier means. i
